El resultado de 79 mas X igual 452 es 141
Answer:
39 / 3 = 13
Step-by-step explanation:
first find out how many times 39 goes into 3 by writing the multiplication facts of 3.
3x1=3 3x8=24
3x2=6 3x9=27
3x3=9 3x10=30
3x4=12 3x11=33
3x5=15 3x12=36
3x6=18 <u>3x13=39</u>
3x7=21 3x14=42
You use 3x13 because 3x13 equals to 39 and that is our dividend.
The answer is 13
The surface area of cylinder is 8.625
, if the cylinder has 5 centimeters high and 1.5 cm of diameter.
Step-by-step explanation:
The given is,
Cylinder has a 5 centimeters height
Diameter of the cylinder is 1.5 centimeters
Step:1
Formula for the surface area of cylinder is,
......................................(1)
Where,
h - Height of cylinder
r - Radius of cylinder
From the values of h and r,

= 
r = 0.75 cm
From the formula,
= ( 2 ×
× 0.75 × 5 ) + ( 2 ×
×
)
= ( 7.5
) + ( 1.125
)
A = 8.625

Result:
The surface area of cylinder is 8.625
, if the cylinder has 5 centimeters high and 1.5 cm of diameter.
